CROSS-REFERENCE TO RELATED APPLICATION

This application is the United States national phase of International Application No. PCT/US2019/041164 filed Jul. 10, 2019, the entire disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND 1. Technical Field

This disclosure relates generally to transaction processing and, in some non-limiting aspects or embodiments, to systems, methods, and computer program products for communicating transaction data between mobile devices.

2. Technical Considerations

Mobile point-of-sale (POS) systems have been developed to enable individuals to process payment transactions. For example, mobile POS systems may connect to mobile devices such as tablets or smartphones that are configured to communicate information to and from the internet via wired or wireless data connections (e.g., Wi-Fi®, third-generation (3G) mobile networks, fourth-generation (4G) mobile networks, and/or the like). Such mobile POS systems may read information from credit cards or debit cards and, in response, communicate such information, along with other transaction-specific data, via the wired or wireless data connections to a remote system for processing.

However, similar to traditional POS systems, once the mobile POS systems read the information from the credit or debit cards, the transaction may be finalized by having the buyer in possession of the credit or debit card engage the mobile device to input additionally-requested information (e.g., a personal identification number (PIN) and/or a signature). As a result, communication with the buyer, particularly via the mobile device, may be limited once payment information is communicated to the POS terminal. Parties such as transaction service providers, issuer institutions, and acquirer institutions, in turn, may rely on only the information received at the mobile POS terminal while the buyer is present to verify the accuracy of the credit or debit card information. This reliance may lead to increases in transaction processing time, both at the POS terminal (when waiting for additional input from the user) and while the transaction is being processed by the transaction service provider.

Provided are improved systems, methods, and computer program products for communicating transaction data between mobile devices. In some non-limiting aspects or embodiments, a user device and a POS device may register with a transaction service provider system to enable the transaction service provider system to coordinate transactions therebetween. Registration may include, among other steps, identifying a correspondence between account data associated with an account (e.g., an account of a consumer or a merchant) and device data associated with a device (e.g., the user device or the POS device). In such an example, the device data may include a unique device identifier (e.g., a phone number, media access control (MAC) address, and/or the like) that is associated with the account data registered to that device by the transaction service provider system. As a result, where the user device or POS device are unable to communicate with one another (e.g., where one or the other computing device is only able to communicate during a transaction via an SMS messaging service and the other is only able to communicate via a data connection), the transaction service provider system may act as an intermediary and enable communication therebetween. This, in turn, reduces and/or eliminates the need for the regression to legacy transaction processing techniques (e.g., the use of paper money and/or other paper financial instruments that may be more readily misplaced, misread, and/or the like), and allows for quicker and more secure access to systems for performing transactions (e.g., a transaction service provider system).

Referring now to FIGS. 3A and 3B, and with continued reference to FIG. 1, illustrated is a flow diagram of a process 300 for communicating transaction data between mobile devices. In some non-limiting aspects or embodiments, one or more steps and/or operations associated with process 300 may be performed (e.g., completely or partially) by user device 102, POS device 104, and/or transaction service provider system 112 (see FIG. 1). In some non-limiting aspects or embodiments, one or more of the steps and/or operations associated with process 300 may be performed (e.g., completely or partially) by another device or group of devices separate from, or including, merchant system 106, payment gateway system 108, acquirer system 110, and/or issuer system 114. In some non-limiting aspects or embodiments, user device 102 may be used as a POS device as described herein and/or POS device 104 may be used as a user device as described herein.

As described herein, the phrase “push payment” may refer to payments during which a first device (e.g., user device 102, POS device 104, and/or the like) initiates a transaction to transfer funds from an account associated with the first device to an account associated with a second device (e.g., another of user device 102, POS device 104, and/or the like). Similarly, as described herein, the phrase “pull payment” may refer to payments during which a first device (e.g., user device 102, POS device 104, and/or the like) initiates a transaction to transfer funds from an account associated with a second device (e.g., another of user device 102, POS device 104, and/or the like) to an account associated with the first device. Accordingly, in some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may both initiate a push payment or a pull payment.

As shown in FIG. 3A, at step 302, process 300 may include registering user device 102 and POS device 104. In some non-limiting aspects or embodiments, transaction service provider system 112 may register user device 102 and POS device 104. For example, transaction service provider system 112 may receive account data associated with an account of a user (e.g., a credit account, a debit account, a currency associated with a credit or debit account, and/or the like) as well as device data associated with user device 102, the device data including a unique device identifier (e.g., a phone number, media access control (MAC) address, and/or the like) from user device 102. Similarly, transaction service provider system 112 may receive account data associated with an account of a merchant as well as device data associated with POS device 104 from POS device 104. In some non-limiting aspects or embodiments, a user with user device 102 and/or a merchant associated with POS device 104 may initiate a telephone call (e.g., using user device 102, POS device 104, and/or another computing device capable of initiating telephone calls) to transaction service provider system 112 to register user device 102 and/or POS device 104. In such examples, transaction service provider system 112 may receive account data and a unique device identifier from user device 102 and/or POS device 104 based on the user and/or the merchant providing input to user device 102 and/or POS device 104.

In some non-limiting aspects or embodiments, transaction service provider system 112 may receive confirmation data associated with confirmation of a transaction, the confirmation data including a unique confirmation code (e.g., a personal identification number (PIN), a predetermined code (e.g., a card verification code (CVC), and/or the like), data associated with a Consumer Device Cardholder Verification Method (CDCVM)), and/or the like from user device 102 and/or POS device 104. In such an example, transaction service provider system 112 may later compare data received from user device 102 and/or POS device 104 during a transaction to the confirmation data received during registration of user device 102 and/or POS device 104 to determine whether the individual operating user device 102 and/or POS device 104 is authorized to do so and, by extension, whether or not the transaction is a valid transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may register an application with user device 102 and/or POS device 104. For example, transaction service provider system 112 may register the application before or after the application is installed on user device 102 and/or POS device 104, and the application may be used to facilitate communication of data between user device 102 and/or POS device 104 during a transaction as described herein.

In some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may be registered with an issuer system 114. For example, an individual may provide device data associated with a user device to issuer system 114 (e.g., in person, via a telephone call, and/or the like). In such an example, issuer system 114 may associate the device data associated with the user device with account data associated with the account of the user. Additionally, or alternatively, an individual may provide device data associated with a POS device to issuer system 114 (e.g., in person, via a telephone call, and/or the like). In such an example, issuer system 114 may associate the device data associated with the POS device with account data associated with the account of the merchant. In such examples, the individual registering the device data with issuer system 114 may also register confirmation data associated with confirmation of a transaction with issuer system 114. Additionally, or alternatively, issuer system 114 may associate the device data of user device 102 and/or POS device 104 with an account token corresponding to the account of the user and/or the account of the merchant, respectively.

In some non-limiting aspects or embodiments, transaction service provider system 112 may store account data associated with an account of a user in relation to device data associated with user device 102. Additionally, or alternatively, in some non-limiting aspects or embodiments, transaction service provider system 112 may store account data associated with an account of a merchant in relation to device data associated with POS device 104. As a result of storing the account data in association with the device data for user device 102 and POS device 104, transaction service provider system 112 may determine that account data associated with the account of the user corresponds to device data associated with the user device and/or that the account data associated with the account of the merchant corresponds to device data associated with POS device 104. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit the account token corresponding to account data of the user to user device 102 and/or transmit the account token corresponding to account data of the merchant to POS device 104.

As further shown in FIG. 3A, at step 304, process 300 may include receiving transaction data associated with a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may receive transaction data associated with a transaction from user device 102 and/or POS device 104. The transaction data associated with the transaction may comprise: device data associated with the device transmitting the transaction data (e.g., user device 102, POS device 104, and/or the like), device data associated with a device corresponding to an account to or from which funds are to be transferred (e.g., user device 102, POS device 104, and/or the like), and/or parameter data associated with the transaction (e.g., a description of goods and/or services purchased, a value of goods and/or services purchased, a transaction value, and/or the like). In some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may generate transaction data based on receiving input from user device 102 and/or POS device 104. In some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may generate and transmit an SMS message and/or a data message to transaction service provider system 112. For example, user device 102 and/or POS device 104 may generate and transmit an SMS message and/or a data message to transaction service provider system 112, the SMS message and/or the data message including the transaction data associated with the transaction. In such an example, user device 102 and/or POS device 104 may transmit the SMS message and/or the data message via an SMS communication connection and/or a data communication, respectively, to transaction service provider system 112.

In some non-limiting aspects or embodiments, prior to transaction service provider system 112 receiving transaction data, user device 102 and/or POS device 104 may communicate with each other via a short-range wireless communication connection and/or via communication network 116 in order to exchange the transaction data associated with a transaction. For example, user device 102 may establish a short-range wireless communication connection with POS device 104 and, upon establishment, transmit device data associated with user device 102 and/or transaction parameters associated with the transaction to POS device 104. In some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may determine that the other of user device 102 and/or POS device 104 is not registered with transaction service provider system 112. For example, user device 102 and/or POS device 104 may determine that the other of user device 102 and/or POS device 104 is not registered with transaction service provider system 112 by transmitting the transaction data associated with the transaction to transaction service provider system 112. In such an example, user device 102 and/or POS device 104 may receive a message from transaction service provider system 112 indicating that user device 102 and/or POS device 104 are not registered with transaction service provider system 112.

In some non-limiting aspects or embodiments, transaction service provider system 112 may determine that a device associated with a transaction is not registered with transaction service provider system 112 (e.g., that user device 102 and/or POS device 104 are not registered with transaction service provider system 112). For example, transaction service provider system 112 may determine that user device 102 and/or POS device 104 are not registered with transaction service provider system 112 and, based on the determination, transmit a message associated with the transaction to user device 102 and/or POS device 104 to indicate that user device 102 and/or POS device 104 are not registered with transaction service provider system 112. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit a message including instructions for how to register with transaction service provider system 112 based on determining that the device is not registered with transaction service provider system 112.

In some non-limiting aspects or embodiments, transaction service provider system 112 may determine that an account corresponds to a transaction. For example, transaction service provider system 112 may determine that an account corresponds to a transaction based on receiving the transaction data associated with the transaction from user device 102 or POS device 104. In such an example, transaction service provider system 112 may determine that a transaction authorization limit (e.g., a limit up to which transactions may be processed with funds from an account) applies to the transaction.

As further shown in FIG. 3A, at step 306, process 300 may include determining whether sufficient funds are available to satisfy a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may determine whether sufficient funds are available to satisfy a transaction based on determining the transaction authorization limit applies to the transaction. In some non-limiting aspects or embodiments, to determine that the transaction authorization limit applies to the transaction, transaction service provider system 112 may transmit a pre-authorization request message to issuer system 114 requesting a transaction authorization limit for the transaction and, based on transmitting the pre-authorization request message, may receive a pre-authorization response message including the transaction authorization limit. Additionally, or alternatively, transmitting the pre-authorization request message associated with the transaction to issuer system 114 may cause issuer system 114 to transmit a pre-authorization response message including an indication as to what amount of funds are available for the transaction. Where transaction service provider system 112 determines that sufficient funds are available to satisfy a transaction (e.g., that the transaction authorization limit is greater than a transaction amount; “YES” at step 306), a first confirmation message associated with confirmation of the transaction data may be transmitted. Alternatively, where transaction service provider system 112 determines that sufficient funds are not available to satisfy the transaction (e.g., that the transaction authorization limit is less than the transaction amount; “NO” at step 306), at step 307 transaction service provider system 112 may terminate the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit a message indicating the transaction was terminated to user device 102 and/or POS device 104.

As further shown in FIG. 3A, at step 308, process 300 may include transmitting a first confirmation message associated with confirmation of transaction data associated with a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit a first confirmation message associated with confirmation of a transaction to confirm that the transaction data is correct. For example, transaction service provider system 112 may transmit the first confirmation message to user device 102 and/or POS device 104 to confirm that the transaction data is correct. In such an example, user device 102 and/or POS device 104 may display a prompt to cause an individual and/or a merchant to input, via user device 102 and/or POS device 104, respectively, an indication that the transaction data is correct or not correct. For example, where transaction service provider system 112 receives transaction data associated with a transaction from POS device 104 requesting that funds be transferred from an account associated with user device 102 to an account associated with POS device 104 (e.g., a request to initiate a pull payment), transaction service provider system 112 may generate the first confirmation message associated with confirmation of the transaction and transmit the first confirmation message to user device 102 to confirm the transaction data is correct. Alternatively, for example, where transaction service provider system 112 receives transaction data associated with a transaction from user device 102 requesting that funds be transferred from the account associated with user device 102 to the account associated with POS device 104 (e.g., request to initiate a push payment), transaction service provider system 112 may generate a first confirmation message associated with confirmation of the transaction and send the first confirmation message to POS device 104 to confirm the transaction data is correct. In some non-limiting aspects or embodiments transaction service provider system 112 may transmit a first confirmation message as an SMS message and/or a data message to user device 102 and/or POS device 104 via an SMS communication connection and/or a data communication, respectively.

In some non-limiting aspects or embodiments, a first confirmation response message associated with confirmation of a transaction may be generated. For example, user device 102 and/or POS device 104 may generate a first confirmation response message associated with confirmation of the transaction. In such an example, user device 102 and/or POS device 104 may generate the first confirmation response message associated with a transaction based on receiving the indication that the transaction data is or is not correct. In such examples, user device 102 and/or POS device 104 may transmit the first confirmation response message to transaction service provider system 112.

As further shown in FIG. 3A, at step 310, process 300 may include receiving a first confirmation response message. In some non-limiting aspects or embodiments, transaction service provider system 112 may receive a first confirmation response message indicating that the transaction data is or is not correct and, by extension, is or is not approved. In such an example, the first confirmation message may be transmitted by user device 102 or POS device 104 to transaction service provider system 112. In some non-limiting aspects or embodiments, user device 102 or POS device 104 may transmit the first confirmation response message to transaction service provider system 112 as an SMS message and/or a data message via an SMS communication connection and/or a data communication, respectively.

As further shown in FIG. 3A, at step 312, process 300 may include determining whether a first confirmation response message confirms a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may determine that the first confirmation response message confirms a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may generate a message associated with the transaction based on determining that the first confirmation response message confirms the transaction. For example, transaction service provider system 112 may generate a message associated with a transaction indicating that a transaction was approved or not approved and, after generation, may transmit the message to user device 102 and/or POS device 104. As further shown in FIG. 3, at step 313, process 300 may include terminating a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may terminate the transaction based on the first confirmation response message.

As shown in FIG. 3B, at step 314, process 300 may include determining whether a transaction is a high-value transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may determine that a transaction is a high-value transaction (e.g., the transaction is associated with a transaction amount greater than a predetermined value, and/or the like). For example, in some non-limiting aspects or embodiments, transaction service provider system 112 may determine that a transaction is a high-value transaction based on the transaction parameters included in the transaction data associated with the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may determine that the transaction is a high-value transaction based on receiving the first confirmation response message.

In some non-limiting aspects or embodiments, a second confirmation message associated with a transaction may be generated to confirm the identity of an individual operating a device during the transaction. For example, transaction service provider system 112 may generate the second confirmation message. In some non-limiting aspects or embodiments, transaction service provider system 112 may generate the second confirmation message based on determining that the transaction is a high-value transaction. In one such example, POS device 104 may transmit transaction data associated with a transaction requesting funds be transferred from an account associated with a user to an account associated with a merchant (e.g., a pull request), and based on receiving the transaction data, transaction service provider system 112 may generate a second confirmation message to be sent to user device 102 to confirm the identity of the user operating user device 102. In another example, where user device 102 transmits transaction data associated with a transaction requesting funds be transferred from an account of a user to an account of a merchant (e.g., a push request), transaction service provider system 112 may generate the second confirmation message to be sent to user device 102 to confirm the identity of the individual operating user device 102.

In some non-limiting aspects or embodiments, transaction service provider system 112 may generate the second confirmation message based on determining that one or more transactions were processed that were not high-value transactions. For example, transaction service provider system 112 may determine that one or more transactions processed within a predetermined period of time leading up to the current transaction satisfies a transaction threshold amount (e.g., an amount of transactions less than, equal to, or greater than a predetermined amount). Where transaction service provider system 112 determines that the one or more transactions processed within a predetermined period of time leading up to the current transaction satisfies a transaction threshold amount, transaction service provider system 112 may generate and transmit the second confirmation message to user device 102 and/or POS device 104. Where transaction service provider system 112 determines that the one or more transactions processed within a predetermined period of time leading up to the current transaction does not satisfy a transaction threshold amount, transaction service provider system 112 may not generate the second confirmation message.

In some non-limiting aspects or embodiments, the second confirmation message may include a request for data associated with verification of the identity of an individual. For example, the second confirmation message may include a request for data associated with verification of the identity of an individual operating the device that transmitted the transaction data to transaction service provider system 112. Additionally, or alternatively, the second confirmation message may include a request for data associated with verification of the identity of an individual operating another device involved in the transaction (e.g., where a first device is POS device 104 that is sending a request for funds from an account associated with a second device such as user device 102, the second confirmation message may include a request for data associated with the verification of the identity of an individual operating the another device (e.g., user device 102). In some non-limiting aspects or embodiments, transmitting the request for data associated with verification of the identity of an individual may cause the device that receives the request to generate Consumer Device Cardholder Verification Method (CDCVM) data and transmit the CDCVM data to transaction service provider system 112. For example, transaction service provider system 112 may transmitting the request for data associated with verification of the identity of an individual operating user device 102. In such an example, user device 102 may generate CDCVM data associated with the identity of the individual operating user device 102 (e.g., a fingerprint of the individual, a passcode, and/or the like). User device 102 may transmit the CDCVM data to transaction service provider system 112 to verify the identity of the individual operating user device 102. Similarly, in some non-limiting aspects or embodiments, transaction service provider system 112 may transmitting the request for data associated with verification of the identity of an individual operating POS device 104. In such an example, POS device 104 may generate CDCVM data associated with the identity of the individual operating POS device 104. POS device 104 may transmit the CDCVM data to transaction service provider system 112 to verify the identity of the individual operating POS device 104.

As further shown in FIG. 3B, at step 316, process 300 may include transmitting a second confirmation message. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit a second confirmation message associated with a transaction to user device 102 and/or POS device 104. In some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may receive input and, based on the input, may generate confirmation data associated with confirmation of the transaction. User device 102 and/or POS device 104 may then generate a second confirmation response message associated with the transaction, and the second confirmation response message may include the confirmation data associated with confirmation of the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit the second confirmation message to user device 102 and/or POS device 104 as an SMS message and/or a data message via an SMS communication connection and/or a data communication, respectively.

In some non-limiting aspects or embodiments, confirmation data associated with confirmation of a transaction may include data associated with an identity of an individual operating a device. For example, in some non-limiting aspects or embodiments, confirmation data may include data received as input at user device 102 and/or POS device 104 that may be used to identify an individual operating user device 102 and/or POS device 104. For a detailed description of verifying the identity of an individual, reference may be made to PCT Patent Application No. PCT/GB2019/051011, filed on Apr. 5, 2019, the disclosure of which is hereby incorporated by reference in its entirety.

In some non-limiting aspects or embodiments, transmitting a second confirmation message may include initiating a telephone call between transaction service provider system 112 and user device 102. For example, where user device 102 and/or POS device 104 are configured to communicate via an SMS communication connection, transaction service provider system 112 may cause a telephone call to be initiated (e.g., an automated telephone call) with user device 102 and/or POS device 104 to receive the confirmation data associated with confirmation of the transaction. In such an example, an individual operating user device 102 may communicate with transaction service provider system 112 to provide confirmation data associated with confirmation of the transaction to transaction service provider system 112.

As further shown in FIG. 3B, at step 318, process 300 may include receiving a second confirmation response message associated with a transaction to confirm the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may receive a second confirmation response message from user device 102 or POS device 104. In such an example, the second confirmation response message may include the confirmation data associated with confirmation of the transaction. In some non-limiting aspects or embodiments, user device 102 or POS device 104 may transmit the second confirmation response message to transaction service provider system 112 as an SMS message and/or a data message via an SMS communication connection and/or a data communication, respectively.

As further shown in FIG. 3B, at step 320, process 300 may include determining whether a second confirmation response message associated with a transaction indicates that a transaction is valid. In some non-limiting aspects or embodiments, transaction service provider system 112 may determine whether the second confirmation response indicates whether the transaction is valid based on comparing the confirmation data included in the second confirmation response message with the confirmation data received during registration of the device transmitting the second confirmation response message. For example, to determine that the second confirmation response message is valid, transaction service provider system 112 may compare confirmation data included in the second confirmation response message received from user device 102 or POS device 104 with confirmation data received during registration of user device 102 and/or POS device 104, respectively.

As further shown in FIG. 3B, at step 321, process 300 may include terminating a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may terminate a transaction based on determining that the transaction is or is not valid. In such an example, the determination that the transaction is or is not valid may include comparing the confirmation data included in the second confirmation response message to the confirmation data received during registration of the device transmitting the second confirmation response. Where transaction service provider system 112 determines that the transaction is not valid, transaction service provider system 112 may terminate the transaction.

In some non-limiting aspects or embodiments, transaction service provider system 112 may re-transmit the second confirmation message to user device 102 and/or POS device 104. For example, transaction service provider system 112 may re-transmit the second confirmation message to user device 102 and/or POS device 104 based on determining that the transaction is or is not valid based on the second confirmation response. In such an example, transaction service provider system 112 may receive another second confirmation response message and, based on the other second confirmation response message, may determine that the transaction is or is not valid.

As further shown in FIG. 3, at step 322, process 300 may include processing a transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may process a transaction. For example, transaction service provider system 112 may process the transaction based on the transaction data associated with a transaction. In such an example, when processing the transaction, transaction service provider system 112 may generate an authorization request message associated with authorization of the transaction and, upon generation, transmit the authorization request message to issuer system 114. Issuer system 114 may, in response to receiving the authorization request message, generate an authorization response message including an indication as to whether the transaction is approved or not approved, and transmit the authorization response message to transaction service provider system 112.

As further shown in FIG. 3, at step 324, process 300 may include transmitting a transaction confirmation message indicating whether a transaction was successfully processed or not successfully processed. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit the transaction confirmation message to user device 102 and/or POS device 104. For example, transaction service provider system 112 may transmit the transaction confirmation message to user device 102 and/or POS device 104 based on receiving the authorization response message. The transaction confirmation message may indicate that a transaction was approved or not approved. In some non-limiting aspects or embodiments, transaction service provider system may transmit the transaction confirmation message to user device 102 and/or POS device 104 as an SMS message and/or a data message via an SMS communication connection and/or a data communication, respectively.

In some non-limiting aspects or embodiments, an electronic receipt may be transmitted. For example, POS device 104 may transmit an electronic receipt to user device 102. In such an example, POS device 104 may transmit the electronic receipt upon successful processing of a transaction. POS device 104 may transmit the electronic receipt to an electronic wallet on user device 102 and/or to an application executed on user device 102 from an electronic wallet on POS device 104 and/or an application executed on POS device 104. In some non-limiting aspects or embodiments, where user device 102 and POS device 104 have an application installed thereon to manage communication of transaction data between mobile devices, the application may be configured to automatically transmit and/or receive electronic receipts upon successful processing of a transaction.

In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit historical transaction data associated with one or more historical transactions to user device 102 and/or POS device 104. For example, in some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may receive input indicating a request for historical transaction data associated with one or more historical transactions (e.g., one or more transactions in which user device 102 and/or POS device 104 were used to facilitate a transaction). In some non-limiting aspects or embodiments, user device 102 and/or POS device 104 may transmit a request to transaction service provider system 112 to cause transaction service provider system 112 to transmit the historical transaction data to user device 102 and/or POS device 104. Upon receipt, user device 102 and/or POS device 104 may display the historical transaction data associated with the one or more transactions on an output component of user device 102 and/or POS device 104. In some non-limiting aspects or embodiments, a request may include a request for historical transaction data associated with one or more historical transactions to which the device requesting the historical transaction data was not a direct party (e.g., one or more POS devices 104 operating under the control of a merchant, such as POS devices 104 assigned to one or more employees of a merchant). In some non-limiting aspects or embodiments, transaction service provider system may transmit the historical transaction data associated with the one or more historical transactions to user device 102 and/or POS device 104 by including the historical transaction data associated with the one or more historical transactions in an SMS message and/or a data message transmitted to user device 102 and/or POS device 104 via an SMS communication connection and/or a data communication, respectively.

In some non-limiting aspects or embodiments, transaction service provider system 112 may maintain reports on behalf of POS device 104. For example, transaction service provider system 112 may store data associated with one or more transactions that were processed using POS device 104. In such an example, transaction service provider system 112 may generate one or more reports based on the data associated with the one or more transactions that were processed and transmit the reports to POS device 104 and/or merchant system 106 to enable a merchant operating POS device 104 and/or merchant system 106 to track payments for accounting purposes, for use as proof of business activity when applying for credit, for use when analyzing trends, and/or the like. In some non-limiting aspects or embodiments, another POS device 104 a may maintain historical transaction data on behalf of one or more POS devices 104 and/or may generate one or more reports based on the historical transaction data of the one or more POS devices 104.

In some non-limiting aspects or embodiments, POS device 104 may be used to initiate a telephone call to register with transaction service provider system 112 (e.g., via an automated registration system configured to receive account data via audio and/or digital input provided by the user at POS device 104). In some non-limiting aspects or embodiments, in response to receiving account data associated with the account of the merchant and device data associated with POS device 104, transaction service provider system 112 may generate an account token and transmit the account token (e.g., as data or over a telephone call), and the account token may be linked to the account of the merchant and the device data associated with POS device 104. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit confirmation data associated with confirmation of a transaction to POS device 104.

With continued reference to reference numbers 402 and 404 in FIG. 4, transaction service provider system 112 may generate an account token for each device during registration. The account token may be linked to the account data for each respective device. In some non-limiting aspects or embodiments, transaction service provider system 112 may provide confirmation data associated with confirmation of a transaction to user device 102 and/or POS device 104 (e.g., transaction service provider system 112 may generate the confirmation data and transmit the confirmation data to user device 102 and/or POS device 104).

As shown by reference number 406 in FIG. 4, transaction service provider system 112 may receive transaction data associated with a transaction from POS device 104. Transaction data may include device data associated with user device 102, device data associated with POS device 104, and transaction parameters associated with the transaction from POS device 104. Transaction service provider system 112 may generate a pre-authorization request message associated with the transaction based on the transaction data associated with the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may determine whether POS device 104 and/or user device 102 are registered and, if not registered, transaction service provider system 112 may transmit a message to POS device 104 and/or user device 102 to prompt registration of POS device 104 and/or user device 102.

As shown by reference number 408 in FIG. 4, transaction service provider system 112 may transmit a parameter confirmation message including data associated with one or more parameters of the transaction to verify the accuracy of the transaction parameters to POS device 104. For example, transaction service provider system 112 may transmit the parameter confirmation message to POS device 104 based on receiving the transaction data associated with the transaction. In such an example, the parameter confirmation message may request a parameter confirmation response message be returned to transaction service provider system 112 indicating whether the transaction parameters associated with the transaction are accurate.

As shown by reference number 410 in FIG. 4, transaction service provider system 112 may receive a transaction parameter confirmation response message from POS device 104. For example, POS device 104 may generate the transaction parameter confirmation response message based on receiving the transaction parameter confirmation message, the transaction confirmation response message indicating whether the transaction parameters associated with the transaction are accurate. In some non-limiting aspects or embodiments, the transaction parameter confirmation response message may be generated based on input received at POS device 104.

As shown by reference number 412 in FIG. 4, transaction service provider system 112 may transmit the pre-authorization request message to issuer system 114. For example, to determine that a transaction is permissible (e.g., that sufficient funds are available to satisfy a transaction) transaction service provider system 112 may transmit a pre-authorization request message to cause issuer system 114 to generate a pre-authorization response message associated with the transaction, the pre-authorization response indicating that sufficient funds are or are not available to satisfy the transaction.

As shown by reference number 414 in FIG. 4, transaction service provider system 112 receives a pre-authorization response message associated with the transaction. The pre-authorization response message may indicate that sufficient funds are or are not available to satisfy the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may generate a first confirmation message associated with the transaction based on the pre-authorization response message. In some non-limiting aspects or embodiments, where the pre-authorization response message indicates that sufficient funds are not available, transaction service provider system 112 may transmit a message to user device 102 and/or POS device 104 indicating that insufficient funds are available to satisfy the transaction.

As shown by reference number 416 in FIG. 4, transaction service provider system 112 may transmit the first confirmation message associated with the transaction to user device 102 to confirm transaction parameters of the transaction. In some non-limiting aspects or embodiments, transaction service provider system 112 may transmit the first confirmation message via an SMS communication connection or a data connection to user device 102. User device 102 may generate a first confirmation response based on the first confirmation message. For example, user device 102 may generate a display based on the first confirmation message to prompt a user to input an indication that the transaction is accepted or not accepted. User device 102 may receive input indicating that the transaction is accepted or not accepted and, based on the input, generate the first confirmation response message.

As shown by reference number 418 in FIG. 4, transaction service provider system 112 may receive a first confirmation response message. For example, user device 102 may transmit a first confirmation response message based on receiving input indicating acceptance of a transaction by a user at user device 102. In examples where the first confirmation response message indicates that the transaction is not accepted, transaction service provider system 112 may transmit a message to POS device 104 indicating that the transaction was not accepted.

As shown by reference number 420 in FIG. 4, transaction service provider system 112 may determine that the transaction is a high-value transaction. For example, transaction service provider system 112 may determine the transaction is a high-value transaction based on transaction parameters of the transaction data. Where the transaction is determined to be a high-value transaction (e.g., the transaction value is greater than or equal to a predetermined threshold), transaction service provider system 112 may generate a second confirmation message associated with the transaction. Additionally, or alternatively, where the transaction is determined to be a low-value transaction (e.g., the transaction value is less than or equal to a predetermined threshold), implementation 400 may continue to reference number 426 and transmit an authorization request message to an issuer system 114.

As shown by reference number 422 in FIG. 4, transaction service provider system 112 may transmit the second confirmation message to user device 102. Transaction service provider system 112 may transmit the second confirmation message to user device 102 based on determining that the transaction is a high-value transaction. The second confirmation message may be configured to cause user device 102 to generate a second confirmation response message including confirmation data associated with confirmation of the transaction. User device 102 may generate confirmation data associated with confirmation of the transaction based on input received at user device 102 (e.g., the input may include a unique confirmation code).

As shown by reference number 424 in FIG. 4, transaction service provider system 112 may receive a second confirmation response message from user device 102. For example, in some non-limiting aspects or embodiments, transaction service provider system 112 may receive the second confirmation response message including confirmation data associated with confirmation of the transaction. Transaction service provider system 112 may determine the confirmation data matches confirmation data corresponding to the user device 102 received during registration of user device 102 with the transaction service provider system. Transaction service provider system 112 may then generate an authorization request message associated with the transaction based on the transaction data and then determine that the confirmation data matches confirmation data corresponding to the user device 102 received during registration of user device 102.

As shown by reference number 426 in FIG. 4, transaction service provider system 112 may transmit the authorization request message to issuer system 114.
